[collectd] Problems with Collectd's GenericJMX and Double Quotes

[martin]

Hi all I need some help from your goodselves in the Collectd community. 

I've got a strange one here and I'm having trouble trying to sorting it, I've configured collectd with the GenericJMX plugin and I've got some of the metrics being collected under collectd.myvm1.* e.g.


collectd.myvm1.GenericJMX-memory.jmx_memory-heap-used


However a couple of entries appear under "collectd.myvm1.* e.g.


"collectd.myvm1.GenericJMX-request_processor-ajp-bio-8009\".
"collectd.myvm1.GenericJMX-request_processor-http-bio-8080\".


So I get two collectd top levels one clean and one starting with a double quote e.g. collectd.myvm1.* and "collectd.myvm1.*


I had some issues initially with the ajp-bio and http-bio being surrounded by escaped double quotes but faxm0dem on #collectd helped me out so I got rid those but I can't figure out how to lose the final two surrounding the collectd string. 


Here's my configuration:
